U. S. BUREAU OF FISHERIES 



MACKEREL FISHERY OF THE ATLANTIC COAST s 



That part of tiie 1933 mackerel catch taken by the purse seines and 

 drift gill nets amounted to 29,532,600 pounds, a decrease of 37 per- 

 cent as compared with corresponding statistics for the previous year. 

 The decrease resulted mainly from voluntary curtailment of the 

 fishery on the part of the purse-seine fleet. It is estimated that normal 

 exploitation of the fishery would have produced an increase rather 

 than a decrease in total catch in 1933 as compared with 1932. 



The statistics in the following table were obtained by combining 

 the figures of mackerel landed at Boston and Gloucester, Mass., and 

 Portland, Maine, with those obtained by agents stationed at other 

 ports where mackerel are landed. The figures include approximately 

 1,000,000 pounds of mackerel that were brought to port but not 

 landed due to lack of market. The statistics include the catches made 

 by all purse seine and drift gill net vessels over 5 net tons (Customs 

 measure) and also the catch of the larger of the boats of less than 

 5 net tons. 



Data in the mackerel fishery are also included in the catch of States.
